Question

The velocity of the image when object and mirror both are moving towards each other with velocity 4 ms-1 and 5 ms-1 respectively is ---------------
(a) -14 ms-1 (b) 15 ms-1 (c) -9 ms-1 (d) 14 ms-1​

Answer 1

Explanation:

given:

velocity of image w.r.t ground = 4m/s

velocity of mirror w.r.t ground = 5m/s

To find :

Relative velocity of image with respect to mirror

finding:

using relative velocity concept:

Relative velocity of image with respect to mirror

= Relative velocity of image with respect to ground - Relative velocity of mirror with respect to ground

= -4 - 5 . (Taking velocity of mirror as positive and of image negative because both are moving towards each other)

= -9m/s

(c ) is correct answer
